THE $250,000 EXHAUST

Roo Systems warns your exhaust system could cost you a lot more than you think

Emissions from vehicles have been linked to thousands of deaths per year in Australia and Roo Systems says it has spent years learning how to work with manufacturers’ systems rather than against them.

Removal of emissions systems in late model 4WDs can result in six-figure fines
Roo Systems warns that the internet is a dark and scary place – hiding behind every corner is endless trouble, legal ramifications, and advice that’ll see you not only pulled up by the police, but potentially with eye watering fines for your trouble. It’s something that not only costs people real money, but can end up with irreparable damage being done to 4WDs.
Roo Systems says that perhaps the biggest issue it has seen popping up more and more recently is the idea that vehicles’ emissions systems are something that are best removed altogether and it’s something the company wants to put a stop to right now.

Why they’re there
An unintended side effect of any internal combustion engine is the release of emissions into the atmosphere.
An EGR, Exhaust Gas Recirculator, is one of the most common emissions systems on almost any engine, petrol or diesel. They’re designed to lower combustion temperatures below the levels at which NOx can form. They work by introducing a small amount of spent exhaust gas into the engine cylinder, replacing combustible oxygen and lowering temperatures below where NOx can form.
The other is the DPF, or Diesel Particulate Filter, and it’s the hot-topic of today. Where older systems like EGRs are designed to stop the production of emissions, a DPF is designed to destroy the emissions after they’re made. More specifically they’re designed to reduce diesel soot. That black smoke is essentially a cancerous ash, that while not overly harmful to the environment is deadly to humans. A DPF is designed to catch the particulates while they’re still in the exhaust before injecting diesel in and burning the particulates down to non-harmful sizes.

Why they’re not a problem
Over the last few years Roo Systems says it has done countless testing with and without DPFs fitted to the vehicle and found time after time there’s a negligible performance gain to be had by removing the DPF.
So where does the myth come from? Very rarely a manufacturer will produce a component with issues, says Roo Systems, stating that the most common offender was the N80 HiLux from Toyota which was known to have issues with its DPF system not correctly burning and causing excessive smoke. However, a warranty fix or replacement unit is all it takes to rectify it.
In almost every other make of vehicle, the DPF causes no issues. Roo Systems explains that they are effectively in the same category as a muffler, in theory removing them may help, but the reality is the vehicle, and the air you’re breathing, are far better off with them in place and working correctly.

Why removing them IS a problem
Pollution equipment, like exhaust systems themselves, are fitted for a reason. EGR coolers and DPFs both work to significantly improve the quality of air we breathe. To persuade people not to tamper with these systems there’s a blanket rule that covers disabling any emissions devices on a vehicle and the fines are eye watering.
On the spot, you can be handed a $500 fine for removing your DPF. If you end up in front of a judge that fine can be increased to $22,000. Get caught selling a car with emissions gear moved? That’s a potential $250,000 fine for an individual and up to $1,000,000 for the shop who did the work. Those are eye watering amounts of money, especially when you consider a competent workshop can keep your emissions systems in tip-top shape.
